The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.
Claims15
A work vehicle comprising:
- a frame;
- a commodity container that is supported by the frame;
- a metering system configured to meter a commodity out from the commodity container, the metering system including a metering element and a plurality of commodity tubes configured to receive the commodity from the metering element;
- and
- a covering structure with a panel that is supported on the frame for movement between a first position and a second position, the panel being substantially rigid;
- the panel, in the first position, covering the metering element and the plurality of commodity tubes;
- and
- the panel, in the second position, exposing the metering element and the plurality of commodity tubes.

A work vehicle comprising:
- a commodity container;
- and
- a metering system configured to meter a commodity out from the commodity container, the metering system including a metering element, a support structure, and a latch mechanism with a biasing member;
- the latch mechanism configured move between a latched position and an unlatched position;
- the latch mechanism, in the latched position, retaining the metering element to the support structure;
- the latch mechanism, in the unlatched position, releasing the metering element from the support structure;
- the biasing member biasing the latch mechanism toward the latched position;
- the latch mechanism configured to move the metering element away from the support structure as the latch mechanism moves from the latched position toward the unlatched position.

A metering system for a work vehicle comprising:
- a support structure with a passage;
- a divider member having a barrier wall and a retainer, the barrier wall including a notch, the retainer attaching the divider member to the support structure;
- and
- a rotatable metering element with a shaft and a projection that projects from the shaft substantially in a radial direction, the shaft being removably received within the notch;
- the rotatable metering element configured to rotate within the notch relative to the support structure such that the projection meters out a commodity into the passage of the support structure;
- and
- the barrier wall directing at least some of the commodity into the passage.
